The US presidency was not designed for a man of Obama's racial background. Instead, it was conceived by and for White males, particularly privileged Christian, heterosexual White males. Hence, how might it feel to be the first African-American commander in chief of an imperial and White hegemonic state? Only Obama can answer this question. Only he knows, for example, how it feels to be undermined and called names by conservative Whites, including White males in the US Congress. Due to the social construction of race, which is linked to the lasting legacy of slavery, colonization, and White supremacy, Blacks are represented and treated as less intelligent and less competent than Whites.

MOUNT VERNON, Va. — The costumed characters at George Washington’s gracious estate here are used to handling all manner of awkward queries, whether about 18th-century privies or the first president’s teeth. So when a visitor recently asked an African-American re-enactor in a full skirt and head scarf if she knew Ona Judge, the woman didn’t miss a beat.

Judge’s escape from the presidential residence in Philadelphia in 1796 had been “a great embarrassment to General and Lady Washington,” the woman said, before offering her own view of the matter.

“Ona was born free, like everybody,” she said. “It was this world that made her a slave.”

It’s always 1799 at Mount Vernon, where more than a million visitors annually see the property as it was just before Washington’s death, when his will famously freed all 123 of his slaves. That liberation did not apply to Ona Judge, one of 153 slaves held by Martha Washington.

But Judge, it turned out, evaded the Washingtons’ dogged (and sometimes illegal) efforts to recapture her, and would live quietly in New Hampshire for another 50 years. Now her story — and the challenge it offers to the notion that Washington somehow transcended the seamy reality of slaveholding — is having its fullest airing yet…

…Ms. Dunbar, the author of “Never Caught,” first came across Ona Judge in the late 1990s, when she was a graduate student at Columbia researching free black women in Philadelphia. One day in the archives, she noticed a 1796 newspaper ad offering $10 for the return of “a light Mulatto girl, much freckled, with very black eyes and bushy hair” who had “absconded” from the president’s house.

“I said to myself: ‘Here I am, a scholar in this field. Why don’t I know about her?’” Ms. Dunbar recalled…
